- .GASTER-RETAINING1 DEVICE.

Specification of Letters Patent.

Patented May 1 1, 1909.

Application filed August 26, 1908. Serial No. 450,332.

The present invention is in the nature of a 1 division of the aboveentitled application, and covers one of the embodiments of the inventiondisclosed in said co-pending application.

The principal object of the present invention is to provide a simplestructure, which can be cheaply produced, can be applied to v casters ofthe type now in general use, and.

will efiectively hold a caster in place.

In the accompanying drawings :-Figure 1 is a perspective view of acaster showing the novel retaining device in place thereon. Fig. 2 is alongitudinal sectional view through the same. Fig. 3 is a detailperspective view of retaining device detached from the caster. Fig. 4 isa horizontal sectional View substan tially on'the line 44 of Fig. 2.

Similar reference numerals designate corresponding parts in all thefigures of the drawmgs. 1

In the embodiment disclosed, a caster pintle 5 is employed, to one endof which is connected the usual yoke 6, and in said yoke is journaledthe roller 7. A retaining device is mounted exclusively on the pintle 5,and is formed of a single piece of wire bent into oppositely disposedloops 8 and 9, which embrace the upper or free end of the pintle and aredisposed in overlapping relation as shown. The upper loop 8 has itsopposite sides bent inwardly as shown at 10, and the end of the pintleabove said loop is enlarged as illustrated at 1 1, thus preventingthelongitudinal displacement of the retaining device.

The ends of the loops are provided with retaining arms 12 that aredisposed longitudinally of the pintle, and are arranged on oppositesides thereof in spaced relation to said pintle. 12 are connected bycross portions or rods 13 The free or lower ends of the arms located onopposite sides of the lower ends of the pintle and movable toward andfrom said pintle. A keeper strap 14 is located below the lower ends ofthe arms, and has a central opening 15 through which the pintle passes.This keeper strap is provided with terminal upstanding hooks 16 thatlimit the outward movements of the cross rods 13, and consequently ofthe arms 12. Said cross rods, howeverare movable inwardly, inasmuch asthe hooks 16 do not limit their inward movements, and thusthe arms 12can yield surficiently to permit the retaining device and caster pintleto be inserted into a socket.

From the foregoing, it is thought that the construction, operation andmany advantages of the herein described invention will be apparent tothose skilled in the art, without further description, and it will beunderstood that various changes in the size, shape, proportion and minordetails of construction,

I may be resorted to without departing from the spirit or sacrificingany of the advantages of the invention. 7 Having thus fully described myinvention, what I claim as new, and desire to secure by Letters Patent,is

1. The combination with a caster pintle, of a caster retaining deviceformed of wire and I comprising loops that surround the pintle at oneend, arms carried by the loops and extending longitudinally of thepintle, and a keeper strap mounted on said pintle and engaging with thefree ends of the arms.

2. The combination with a caster pintle, of a retaining device formed ofwire and comprising loops that surround the pintle at one end, armscarried by the loops and extending longitudinally of the pintle, crossbars connecting the free ends of the arms and located on opposite sidesof the pintle, and a keeper strap mounted on the pintle and havingterminal hooks in which the cross bars are movably engaged.

free ends of the arms, the said cross bars be- I my own, I have heretoaflixed my signature ing located on opposite sides of the pintle, I inthe presence of two Witnesses. and a keeper strap having a centralopening T J .7 i through which the pintle passes, said strap DUNOABMACCIJAHL 5 having terminal hooks in which the cross i Witnesses:

bars are loosely engaged. F. A. BARTLING,

In testimony, that I claim the foregoing as GEO. A. ORTGEN.
